CHEAP. FUN.

Building off the incredibly successful inagural SpecFit season we are excited to introduce the next iteration of fun per dollar motorsports with the #GRIDLIFE SundaeCup. Both SpecFit and the SundaeCup are all about bringing motorsports to the masses with a maximum fun per dollar series utilizing affordable daily drivers, a simplified rule set and a balanced field putting focus on the driver vs the build. SpecFit & the SundaeCup will run within the TrackBattle series as a sub classification of the Street class. Drivers will run within the same track time allocated for TrackBattle time attack sessions at #GRIDLIFE Events. SundaeCup will be divided into SubClasses based off entries. 4 entries of any similar chassis will automatically create a subclass for that event. IE: SpecFit, FiestaCup, etc.

SundaeCup 2019 RULES

INTRODUCTION

The #GRIDLIFE SundaeCup is designed to be a tight competition in daily drivers with minimum modification. The SundaeCup is designed to allow any vehicle with a factory power to weight ratio of 25:1 to compete against similar vehicles in a daily driver battle within the Time Attack format of the TrackBattle series. All SpecFit and SundaeCup cars cars must be within the “spirit of the rules” and any car judged by the TrackBattle staff to be outside the bounds of the “spirit” of the rules will be moved to an appropriate class. The “spirit of the rules” is a simple, bolt-on street car.
